Changes to make the ceph-client-no-library branch compatible with bobtail

Working on getting the cuttlefish changes into the cookbooks, but before pushing those to the repo I want to add the needed changes to make bobtail work. The following changes enable the install and use of bobtail instead of argonaut as well as including a few fixes for problems seen while installing ceph bobtail in the field.
